Lesson 13 — Angle of Arrival

The one field in the pulse-descriptor word that says where, not what — and the hardest to measure. We compare amplitude comparison against phase interferometry, derive the interferometer relation, and resolve the accuracy–ambiguity trade with multi-baseline arrays.

Reading

Angle of Arrival

Amplitude comparison, the interferometer relation $\Delta\phi=\frac{2\pi d}{\lambda}\sin\theta$, phase wrap, and multi-baseline.
